I may have been reading it wrong as to what fan it is, will have to check later as I'm away from pc right now.
But my setup for fans is I have the 2 dark rock pro 4 fans on a splitter going to cpu_fan, I have 3 case fans, 2 at front, 1 at rear.
Those case fans are connected to the PCB fan controller which is in the be quiet 900 rev 2 case, that in turn is connected to cpu_opt.
Now when i run hwmonitor software it only shows 3 fans, the middle of the 3 fans is usually the one with very low rpm, but which fan that is is hard to say untill I unplug it later.
There also seems to be no way of controlling cpu_opt, nothing in bios, it just lists cpu_fan plus the chassis ones and a couple of other water ones.
I don't get how it's just showing 3 fans when I have a total of 5, maybe it's reading the splitter on the cooler as 1, but that would make 4 I should see in hwmonitor.
If that's the case then 3 fans on the PCB fan controller going to cpu_opt should be read as 1 only aswell?? Making a total of 2. But I see 3 in hwmonitor software, I don't get how it shows 3 unless those 3 are the case fans, pretty confused.
As far as being on standard mode, the fans will ramp up but whichever fan doesnt appear to be ramping up still won't. There's no way I'm going to run on full speed, the amount of noise is like a server farm.
Forgot to mention, running on a 5800x.
